Sarah is saving to buy a new phone. She needs $150, and she has already saved $63. Write an equation to model this situation. Le

goblinko [34]

Answer: 150-x=63$

Step-by-step explanation:

to solve most missing number equations using addition or subtraction its usually pretty simple

1. figure out the first number. the first number is usually the goal amount. so 150

2. were do i put x? in an equation 150-63 would equal the amount she needs. so when you subtract x from 150 you'd get 63. you already know the goal number 150 goes first and the equation equals 63 so x is going to be whats subtracted from 150

3. put it all together 150(goal)-x(unknown number)=63(the amount she already had)

4.solve 150-87=63

5.check your work 150-63=87

What is the area of the base of a rectangular prism that has a 9mm width an 8mm height and a 14mm length?

const2013 [10]

Answer:

The area of the base is 126 mm².

Step-by-step explanation:

Given:

A rectangular prism that has a 9mm width and 8mm height and a 14mm length.

Now, to find the area of the base of the rectangular prism.

The dimensions of rectangular prism are:

Length = 14 mm.

Width = 9 mm.

Height = 8 mm.

Now, to get the volume of rectangular prism by putting formula:

$Volume=length\times width\times height\\\\Volume=14\times 9\times 8\\\\Volume=1008\ mm^3.$

Thus, the volume of rectangular prism is 1008 mm³.

Now, to get the area of the base we put formula:

$Volume=base\ area\times height \\\\1008=base\ area\times 8$

Dividing both sides by 8 we get:

$126=base\ area\\\\Base\ area = 126\ mm^2.$

Therefore, the area of the base is 126 mm².

The Mean will decrease while the Median and the Mode will remain with the same amount.

For Central Measures, we have Median, Mode and Mean. They try to describe the whole distribution by one value, in the center of it.

For this question, let's pick some examples from the Old Faithful, WY Station to the National Oceanic and Atmospheric Administration from 2015, January

1st Case Scenario:

For 7 days of precipitation, (Snow, ice pellets, etc. rain) in inches:

19 19 19 24 23 23 23 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Mean = 5

Median=0 (the sum of the 15th+16th position over 2)

Mode=0 (Most common observations)

2nd Case Scenario

For 3 days of precipitation, (Snow, ice pellets, etc. rain) in inches:

0 0 0 24 0 0 23 0 19 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Mean = 2.2

Median =0

Mode=0
